Answer:
Explanation:
Electric field E = k Q / R²
k = 9 x 10⁹ , Q is charge and R is distance of point from the charge where field is to be found .
Electric field due to q₁ at distance x where total field is zero
E₁ = k x .48 x 10⁻⁹ / x²
Electric field due to other charge at that point
E₂ = k x 7.6 x 10⁻⁹ /( 1.16-x )²
For net field to be zero , E₁ and E₂ should be equal and opposite
k x .48 x 10⁻⁹ / x² = k x 7.6 x 10⁻⁹ /( 1.16-x )²
(1.16 - x )² / x² = 7.6 / .48 = 15.8333
1.16 - x / x = ±3.979
1.16 - x = 3.979 x
1.16 = 4.979 x
x = .233 m
distance from other charge
= 1.16 - .233
= .927 m .
